Stepped into Trader Joe’s last evening around 7 pm with a friend. We were going to ‘buy dinner’ and dine in. As we stepped inside the door, I thought it strange that shoppers with carts at varying degree of ‘full’ were not milling, but rather standing stationary by the door. Friend immediately said “I’m not doing this”, and turned to leave. I did not grasp what he meant, nor could I process what I was seeing. As I too turned to leave, I asked what was wrong? ‘That’s the end of the line’, he said. I looked back and then realized what I was seeing: parallel lines that ended at the door, but snaked through the store in order to check out. That is shopper commitment!
